Polhemus FastScan FastScan 結合了Fastrakr 動態追蹤的技術，用來偵測物體的所在位置及方 位，經過偵測描掃下來的物件影像，可以透過電腦系統建置 3D 物體。FastScan 可以掃瞄以往無法掃描的地方，也可以掃瞄移動 中的物體，且對於非金屬物體掃  瞄的效果是非常的理想
分析 過程 | Custom electronics video processor Polhemus FASTRAK® magnetic tracker | 尺寸 | 450 mm (18 in) in length 2 miniature monochrome cameras
1 laser diode: 670 nm, 1 mW, Class II Tracker Receiver | 解析度 | Laser line length increases with Wand-Object range, typically ..150 mm at 200 mm range (6 in at 8 in) Resolution along the laser line depends on Wand-Object range, typically 0.5 mm at 200 mm range (0.02 in at 8 in)
Scanning speed is 50 lines/sec, line-to-line resolution depends on scanning speed, typically 1 mm at 50 mm/sec (0.04 in at 2 in/sec). Resolution | 系統 | Tracker Transmitter Tracker Receiver for attachment to movable objects | 範圍 | Up to 760 mm (30 in) Wand-Transmitter and Receiver - Transmitter range
75 mm to 680 mm (3 in to 27 in) Wand-Object range | 準確度 | With Transmitter as Reference, accuracy depends on Wand-Object range, typically 1 mm at 200 mm range (0.04 in at 8 in)
With Receiver as Reference, accuracy also depends on Receiver-Object range | 界面 | Connects to ECP capable parallel port (LPT1), additional card available (LPT2) DMA ECP driver provided | 軟體 | 3D graphics: point, wireframe, flat or smooth surface display 3D controls: rotate, zoom, center scan Selectable resolution, faceted surface simplification, outlier removal Export polygon mesh to 3D Studio Max®, ASCII Points, AutoCAD Points and 3D Faces, IGES Points, Lightwave Object, Matlab Mesh, STL, Virtual Reality Modeling Language, Wavefront Object, Open Inventor and others. | 環境 | Operation in the presence of metal objects or electromagnetic fields may interfere with the scanner's tracking and degrade performance. Providing the Transmitter, Wand and Receiver are kept sufficiently far from metal objects or fields they should not pose a problem. Because scanning relies on the cameras seeing the laser line, some surfaces may not be suitable for laser scanning, eg. translucent, reflective, dark or deeply convoluted surfaces. | 最低系 統需求 | Pentium II, 266MHz, CD-ROM, 64MB RAM minimum, ECP capable parallel port, Windows NT 4, preferably OpenGL accelerated graphics card |
